 Trustindex verifies that the original source of the review is Google. We had our windows and doors replaced by Sureseal Windows and could not be happier.
We had a home visit from the salesman, who went through the various designs and colours available plus an initial measurement of all the items needed.
Following our agreement to purchase the doors and windows a supervisor visited to precisely measure the openings and look for any issues that might arise during the install.
The fitting was booked in about 10 weeks later.
Alan contacted us to give his ETA of the morning of the start of the job. And we cannot praise Alan enough for his work and cleaning up after. All areas where work was done were covered with dust sheets and no mess was left.
There were a couple of remedial jobs to be completed when the parts were available.
Sean completed these jobs for us over a coarse of a morning. And, as with Alan previously Sean's work was great and all was cleaned up on completion.
Both workers are a credit to SureSeal. And we highly recommend the Company.

 Trustindex verifies that the original source of the review is Google. From initial call from Sureseal making appointments to choosing our windows all the team have been very knowledgeable and helpful, No big sell to get the costs up just what we wanted and even reduced aspects no of closers etc. to meet requirements. Plenty of payment options with full explanation again no push either way.
Survey was again very straightforward and with some discussion even more savings found.
Pleasure to do business with. Great service and very knowledgeable.will post photos of finished project once complete.
